Have imported library from backup - same thing happens
Note sure what you did but you must never IMPORT an iPhoto library into an iPhoto library - you restore backups - you do not import them
The ! indicates that iPhoto has lost the link to the original photo - you could cause that by messing around in the iPhoto library or it can be caused by corruption
Have restored permissions, thumbnails, database etc nothing happening, same old exclaimation mark.
Again not sure what you did - you can not restore those - I'm assuming thatyou depressied the option and command keys and launched iPhoto and rebuilt the database and thrumbnails
If none of those worked and you have not deleted anything then download iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ - and use it's rebuild command ot create a new library - that should resolve but if it does not you will still have your current library to go back to
Using iPhoto Library Manager to Rebuild Your iPhoto Library
- Download iPhoto Library Manager and launch.
- Click on the Add Library button,
navigate to your Home/Pictures folder and select your iPhoto Library folder.
- Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option
- In the next window name the new library and select the location you want it to be placed.
- Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost.
Note: your current library will be left untouched for further attempts at a fix if so desired.
